The presence of weeds in stands aiming at forest restoration can cause harn, as they can compromise the growth of tree species. The objective of this work was to evaluate the efficiency of crowning with cardboard disks to control Urochloa spp. at forest restoration. The survival and growth of eight native tree species and the maintenance costs of manual crowning (T1) and the use of cardboard disks (T2) were evaluated. There was no effect of the cardboard disks when considering the survival and growth of the tree species 9 months after planting. At this age, only 23% of the original cardboard disks mass remained. Costs of cardboard treatment was 65% higher than manual crowning.
